CANE-MILL.

Application filed July 29, 1916.

This invention relates to cane-mills of the class in which an upper roll cooperates with two lower rolls, a front lower roll and a rear lower roll, the rear lower roll being subjected to the action of hydraulicpressure.

One object of my invention isto secure an improved construction of a mill of this class in which the space between the upper roll and the front lower roll will automatically adjust itself during the action of the mill as well, as the space between the upper roll and the rear lower roll, and independently of this latter automatical adjustment and in which, further, the space between the knife or turn-plate and the upper roll will also adjust itself automatically during the action of the mill, in the same direction and in the same proportion as the space between the upper roll and the front lower roll.

And a further object of my invention is to secure this automatical adjustment of the space between the knife or turn-plate and the upper roll without making use of complicated mechanical transmissions or auxiliary means and without the necessity of operating auxiliary manual adjustments during the working of the mill.

Further, another object of my invention is to reduce the wear and tear of the movable parts, which, as it is wellknown, are generally subjected, in the usual constructions to very heavy loads.

With these objects in view, my invention essentially consists in special combinations and arrangements of parts as will be hereinafter fully described and pointed out in the appended claims.

Referring to the annexed drawings, which show as an example, a cane-mill constructed according to my invention.

Figure 1 is a side elevation of the mill and Fig. 2 a longitudinal section of a part of the mill.

The mill comprises, as ordinarily, three rolls: the upper roll A, which in this case,

is mounted in fixedbearings, the front lower roll B and the rear lower C.

The rolls B and C are adapted to automatically adjust themselves during the working of mill, with regard to the fixed upper roll A. These three rolls A-BC are of ordinary and well known constructlon.

The upper roll A rotates in fixed bearings D. The rear lower roll C rests in bear-- ings E, which are supported by blocks F which are subjected to the action of hydraulic pistons contained in the cylinders G. These cylinders are screwed in the lower caps H at each end of the main frame V of the mill. 1

The front lower roll B rotates in bearings K which are supported by blocks L sub jected to the action of hydraulicpistons contained in cylinders G, in a manner similar to the arrangement of the cylinders G.

N shows the beam carrying the turn- As shown in Fig. l, the axes of the cylinders G G, of the hydraulic pistons supporting the blocks F and L, are located approximately in the converging planes passing through the axes of the lowerrolls B -G and the axis of the'upper roll A. '.As it is in these planes that the thrust is exerted when the cane passes between the upper roll and the lowerrolls, it will be obvious that when the lower rolls B and C will be displaced, their bearings EK andsupporting blocks FL will slide between their guides without any exaggerated friction.

On the other hand, as the front lower roll B is subjected to the action of hydraulic pistons, said roll will be adapted to adjust itself automatically to the upper roll,

absolutely independently of the automatic adjustment of the rear lower roll. M is the turn-plate, which is mounted on a beam N. This beam is supported by the blocks L of the bearings of. the front lower roll B. To this end, said beam is secured by means of bolts P to two slides O, placed at the right and left hand sides of the roll B and these slides are fixed by means of blots Q, to the supporting-blocks L. In this way, the turn-plate M, together with the beam N, forms a rigid body with the supporting blocks L of the front lower roll B. The turn-plate consequently moves directly and conjointly with the front lower roll during the working of the mill and adjusts itself'automatically'inthe same di--- rection'and in the same proportion as this roll, without it being necessary to proceed to any auxiliary adjustment during the working or to make use of complicated mechanical means or transmitting devices between the bearings of the roll and the beam of the turn-plate to secure a coordination of .movement between the turn-plate and the front lower roll.

I'lhe initial adjustment of the space between the upper roll A and the turn-plate M is effected at rest, no subsequent ,adjustmentbeing required when the mill is working, owing to the solidarity of movements of the front lower roll and of the turnplate.

To allow this initial adjustment, the holes which are provided in the beam N for the reception of the bolts P, are elongated in such a manner that the beam N, together with the turn-plate M, can be somewhat adjusted in the vertical direction by the use of plates R placed between the beam N and the slides 0, 'according to the space which it is desirable to produce between the upper roll "A and the turn-plate M; the plates B being inserted, the bolts P may be tightened I to assemble the beam rigidly with the slides.

In order to vary the position of the turnplate in the-horizontal direction, a key S, 1

aving an inclined face isinserted between the'turn plate M and the beam N; after the insertion of this key, theturn-plate is fixed to the beam N by means ofbolts T.

-' The lower caps H and the upper caps W are attached to the frames V by means of bolts X, also placed in the direction of the thrust upon the rolls.

The frames V are mounted upon a juice collecting vessel Z-by means of bolts A.

Having thus described my invention, what I claim is: y

1. In a cane-mill, an upper fixed roll, a

front lower roll, hydraulic pistons forsaid front lower roll, bearings for said front lower roll, blocks supporting-saidbearings, hydraulic pistons for said blocks, a turnplate rigidly supported by said blocks, a rear 7 lower roll and hydraulic pistons for said rear lower roll.

'3. Ina cane-mill, an upper fixed roll, a front lower roll, bearings for said front lower roll, blocks supportin said bearings, hydraulic pistons for said locks, the axes of said pistons being in. the direction of the thrust upon the roll, a turn-plate rigidly connected to said blocks, a rear lower roll and hydraulic pistons for said rear lower roll. i

4:. In a cane-mill, an upper fixedroll, a front lower roll, bearings for said front lower roll, blocks supporting said bearings, hydraulic pistons for said blocks, the axes of said pistons being in the direction of the thrust upon the roll, a turn-plate, a beam supporting said turn-plate, two slides sup porting said beam, the said slides being rigidly connected with the supporting blocks for the bearings of the front lower roll, a rear lower roll and hydraulic pistons for said rear lower roll. 7

Intestimony whereof-I have affixed my signature in presence of two witnesses.
